I've been playing with the Fosi BT 20 a for 6 months and it's sounding good on every set of speakers I try 😊

[Porco]

Fosi Audio is on the fasttrack to become a serious hifi contender! Been waiting for a TPA3255 Class D in this form factor (without all sorts of VU meters and decorative tubes) with 2 inputs for a while, this might be the one.

[mikecampbell]

Great review as usual Michael. Using real measurements is something very few people do, so kudos to you for a real and honest review! Merry Christmas to you young man!

Im running 2 of these fellas right now and am very happy with them. Ive had some big behemoths over the years with big power, these do all anybody will ever really use and can drive basically anything on the right preamp, keeo in mind rhe preamp is the key, right now the p3 does just fine until they release a balanced matching preamp for these. No complaints, they can run with the pack, for certain. Drove the big flagship polk sda srs 1.2 at 120 db+ levels without any trouble and great composure and tonality to go with it, and those arent an easy speaker to drive into higher spl levels. Cery happy with the za3, just want a balanced preamp to match with orange accents and a remote now!

[marcelwallace]

Do we need a preamp to use it as mono-blocks. And if so, which one. Thank you for your work. Very nice choice of gears ;)

[petertys]

do you notice when the ZA3 volume down the left channel audio is soft compared to the right channel. Please comment. Thanks

me as a broke budget buyer really like the way the industry is going with this. in multiple ways.
1. its a way for me to finally say goodbye to super old used vintage gear because its the only think i can afford...seriously that stuff gets older and older and electronics wont live forever and buying 20+ year old amps can be a gamble.
2. lets say, yes audio quality is important but thats not all. if you look at every other consumer electronics product, things get smaller and things get more efficient and thats a good thing. do you still want a 50kilo heavy crt monitor on your desk? i guess not. and so do i and other people not want a huge roomheater in our living room that drains so much power of the wall you could light up the entire neighborhood. especially that cost of living and electricity becomes more and more expensive... saving becomes more important. electricity has a running cost, space has a running cost too... and if i can have something that does the same thing but smaller and with less cost: great.
3. also i think audio gear was super overpriced. and that might be due to kind of a monopoly where all the big players kind of do the same thing and milk money. ofc they sell nice stuff but come on you cant tell me that a 3000$ amplifier is so damn expensive in manufacturing that is HAS to be that expensive. it is that expensive because people pay money and audiophiles throw away money at everything.
4. also i m tired of spending hours upon hours upon hours tryng to find this one deal on used market and then gamble and hope it wont die in the next year. its so refreshing that you can just go online and buy something because its available and affordable instead of running amps with 20 years old caps in it

A while back I was told the Fosi V3 could run the smaller Magnepans, all the way up to 1.6 at (to quote the guy who told me...) "offensive" volume levels. A speaker that is noted for being extremely power hungry but one that punches well above its price point, so I bought a V3 and planned to upgrade the op amps. I knew monoblocks were coming from Fosi but I never would've dreamed they'd be here this soon. Guess I'm selling the V3 and getting a pair of these soon, for when I invest in a pair of Maggies and a couple of servo subs.

[mikapouramo]

Wonder we ever get real recorded sound tests of your chifi reviews? Just a speech.

[jljaylee]

Thanks Mike! Am lucky to have won the giveaway - I emailed you to claim the P3 but haven't heard back so let me know how best to reach you

[telliott]

Is there something like this I can use with my Kliposch R-15 PM speakers? They are powered and have a bunch of inputs. Unfortunately, the PC digital input died after about a year and recently, the optical input started turning itself off after a few minutes forcing me to use Bluetooth for video sound. Luckil, my Chromecast has Bluetooth support.

[jsherman]

Maybe it's been answered already and I haven't found it, but very basically:

What's the purpose of running theZA3 as monoblocks if the output power rating only goes up 10% or 20%? Shouldn't the power output almost double in bridge mode?

In other words: What's the advantage of buying two and running them in mono mode when the power output is essentially the same? Is this really only meant for people with 2 ohm speakers?

[joaquim]

Hi, thanks for the video! Does anyone knows if ZA3 is a big step up compare to V3 in term of sound (I've a V3 with dual Sparkos 3602 fitted with a 2.1 Q acoustics 3000i series). Cheers guys.

[viencarlodiego]

good day! if i want to run the za3 as monoblocks and want to change the op amps, do i need to change both left and right op amps? thank you!

[lisar]

wait - so all these tests - especially the listening test - were performed with the sparkos op amps in situ?

[ryanchappell]

The binding posts being plastic might be a good thing. You don’t want unnecessary mass there. The important thing is non-ferrous metals. Someone put a magnet on there and see what happens

[arthurriaf]

Hey Mike, your nit pick on binding post color was a cheap shot.
Bibding posts 📫 bind. If they hold the wire, I'm happy. Besides, they take banana jacks you can color match that.
I bought a ZA3 and use it in mono for a dedicated 8" subwoofer.
Any issues with high frequency or noise (which there's none) aren't anywhere to be heard.
Plenty of power with the 42 volt P.S. thanks for the review.

[korling]

Is there any benefit to changing out any of the other opamps besides the right and left channel?

[UlTiReV]

How would you compare the sound to a classic ab amp?
If cost was not a factor, would you choose the ZA3 over a sub 1000 usd class AB?
Thanks!

[korling]

In mono mode, you only need to change the right channel opamp right?
